“…The proposed reactor can utilize variety of fuel cycles and can benefit from a Multilateral Fuel Cycle concept. In conclusion, the FBNR can be considered as a fool proof reactor against nuclear proliferation that the present world is looking for to be assured of both safety and safeguard, extensively outlined in previous work [5][6][7][8].…”

A new era of nuclear energy is emerging through innovative nuclear reactors that are to satisfy the new philosophies and criteria that are being developed by the INPRO program of the International Atomic Energy Agency (IAEA). It is establishing a new paradigm in relation to nuclear energy. The future reactors should meet the new standards in respect to safety, economy, non-proliferation, nuclear waste, and environmental impact. The fixed bed nuclear reactor (FBNR) is a small nuclear reactor that meets all the requirements. It is an inherently safe and passively cooled reactor that is fool proof against nuclear proliferation. It is simple in design and economic. It can serve in a dual purpose plant to produce simultaneously both electricity and desalinated water, thus making it especially suitable to the needs of the Middle-East Countries. FBNR is being developed with the support of the IAEA under its program of small reactors without on-site refueling. The reactor uses the pressurized water reactor technology. It fulfills the objectives of design simplicity, inherent and passive safety, economy, standardization, shop fabrication, easy transportability, and high availability. The inherent safety characteristic of the reactor dispenses with the need for containment; however, a simple underground containment is envisaged for the reactor in order to reduce any adverse visual impact.

“…UC Berkeley developed a liquid salt cooled, high temperature reactor conceptual design, named Pebble Bed Advanced High Temperature Reactor (PB-AHTR) (Lim and Peterson, 2009), to achieve a higher core power density of 20-30 MWth/m 3 , compared to the 4.8-6.0 MWth/m 3 typical of modular helium reactors (MHRs) (Bardet et al, 2008). To apply the PBR design features in most experienced pressurized water reactor (PWR), Sefidvash (1996) firstly presented the concept of small modular fluidized bed light water reactor, and then the concept of fixed bed light water reactor (Sefidvash, 2004). Pacific Northwest National Laboratory (PNNL) (Senor et al, 2007) also has proposed its Atoms For Peace Reactor (AFPR-100) concept for both boiling and pressurized types water reactor.…”

“…The fixed bed nuclear reactor (FBNR) is being developed under the IAEA Coordinated Research Project (CRP) on Small Reactors without On‐site Refueling . The FBNR operates at the 70 MW el capacity, based on the conventional PWR technology, but uses spherical fuel elements, where TRISO particles will be imbedded with fuel kernels in the center.…”

Reactivity and kinetic parameter evolutions for the core height and boron concentration of the fixed bed nuclear reactor

et al. 2016

SUMMARY This article focuses on calculation of reactivity and kinetic parameters in different states (different core heights and boron concentrations in the coolant water) of the fixed bed nuclear reactor (FBNR). The numerical calculations are performed with the SRAC code. Uranium dioxide (UO2) with 235U enrichment grade of 5% is used as spherical fuel pellets in the TRISO fuel type. The core height is changed by a core height level limiter. The main results of this study can be summarized as follows: The effective neutron multiplication coefficient is varied with the core height and boron concentration in the coolant water. When there is no‐boron in the coolant water and the core height is over 120 cm, the reactor control can be carried out by the movement of a core height level limiter, without the fine control rods in the core center; but when there is a boron concentration, the reactor may be controlled by the level limiter at the lower core heights. The kinetic parameters (the prompt‐neutron lifetime and effective delayed neutron fraction) of the reactor also are changed to the reactor core height and to the boron concentration in the coolant water.
